Klyuchi, Kamchatka Krai

In 2004, it was demoted to a rural locality in order to become eligible for increased funding from the Russian federal budget.

Klyuchi, being in a very isolated part of the former Soviet Union, has been near an intercontinental ballistic missile testing range since the Cold War, the Kura Missile Test Range, and is served by Klyuchi air base just southwest of the town.

Klyuchi's original airfield consisted of a dirt airstrip and was located 13 kilometres (8 mi) east-southeast of the town.

Summers are generally mild and rainy with cool nights, while winters are long, cold, and very snowy.

Due to Klyuchi being located in the interior, the maritime influence is less than for Petropavlovsk-Kamchatsky and the nearest coastal locality of Ust-Kamchatsk.
